IMPROVEMENT IN GRAIN THRASHING AND SEPARATING MACHINE.

Specification forming part of Letters Patent- No. 45,676, dated December 27,1864.

To all whom it may concern:

Be it known that I, JosEPH RAYNER, of Piqua, in the county of Miami and State of Ohio, have invented a new and Improved Elevator for Machines for Thrashing and Separating Grain; and I do hereby declare that the following is a full and exact description of the same, reference being had to the accompanying drawings, making part of this specification, in which Figure 1 is a plan of a grain thrasher and separator with my invention attached. Fig. 2 is a vertical section at m m, Fig. 1.

Similar letters of reference indicate corresponding parts in both views.

The nature of my said invention consists in a certain combination and arrangement of devices, hereinafter described, for the purpose of returning the tailin gs to the thrashing-cylinder to be rethrashed. I

To enable others skilled in the art to which my invention pertains to make and use the same, 1 will proceed to describe its construction and operation.

The main frame A, thiashing-cylinder B, chute O, straw-carrier D, shaking-shoe E, and separating-fan F are by preference arranged and operated as set forth in original Patents Nos. 19,865, 24,838, and 26,283, and reissued 5 Patents Nos. 715, 718, and 719, granted to John It. Mofiitt, of Piqua, Ohio, and require no specific description. My invention is, how ever, equally applicable to machines of other 0 )llSlZIUCblOI].

The elevator by which the tailings are returned to the thrashing-cylinder is construct ed as follows: 0 is an inclined box or tube of any suitable form extending from the tailing- 's vout l forward and upward to the conductor P, which discharges in front of the thrashingcylinder. The box 0 is closed on all sides, but open at its ends. Q is a cap covering the upper ends of the box 0, and presenting inward toward the thrashing-cylinder. R is a drum, covering the lower end of the box, and

forming a communication between it and the tailing-spout l. S is a fan, journaled within the drum It and rotated by a belt, 8, from the shaft of the separating-fan F, or in any other suitable manner.

In using this invention the imperfectlythrashed heads and other matters which (being too large or too light to pass into the receptacle for clean grain and too heavy to pass off with the chaff and straw) fall down at the tail of the shaking-shoe, and are commonly known as tailings, are conducted into the 'drum R, and by the centrifugal action of the fan S and a powerful current of air produced thereby are forced upward through the conductor P, and thereby returned to the cylinder B to be rethrashed.

The tailings may be conveyed from the shoe to the conductor and from the conductor to the thrashing-cylinder by any suitable means. The fan S may, if preferred, rotate upon a vertical instead of a horizontal axis, the other modifications may be made without departing from the essential principles of the invention.

I am aware that rotary fans have before been employed for elevating grain in various ways,.and therefore do not desire to be understood as claiming this principle, broadly.

I claim as new and desire to secure by Letters Patent- As an improvement in machines for thrashing and separating grain, the combination of the spout 1, fan S, tube 0, and conductor P, constructed and arranged as specified, and operating in connection with a shakingshoe and thrashing-cylinder, substantially as and for the purposes set forth.

In witness whereof I, the said JOSEPH RAY- NER, have hereunto set my hand this 18th day of March, A. D. 1862.

JOSEPH RAYNER.
